Let's not confuse the air conditioning , heating and ventilation of your Nissan Maxima 4. Heating and air conditioning are mechanisms that offer the possibility of reducing or increasing the temperature. The very first with the help of the heat produced by the engine, and the other with the help of a liquid refrigerant . Your ventilation is the set of channels and systems that give the possibility of air to reach the interior of the vehicle. The main component will be kicker which propels the air inside your cabin. If there is hardly any air at all, it is likely a malfunction of ventilation. We will see thanks to this post how ventilation works, so as to better perceive the concerns and understand by what means to remedy them.
How ventilation works on a Nissan Maxima 4
Ventilation is used to start to regenerate the air inside the interior of your Nissan Maxima 4. For the blower, the latter is usually made of a resistor, a turbine, and a motor. The more the integral resistance of the circuit is reduced, the faster the turbine turns. By turning the knob in the passenger compartment, the resistance is therefore reduced.
Nissan Maxima 4: regular ventilation problems
Dirty air ducts
If the ventilation is working but little air is entering the interior of your Nissan Maxima 4, it is possible that these air flaps are blocked. Using a screwdriver flat, it is possible to remove the air flap valves. Just check in if they are congested. If this is the case it is possible to scour them, but also the shutters.
Dirty cabin filter
When you perceive fumes and the ventilation lacks power, the malfunction probably comes from the cabin filter of your Nissan Maxima 4. It becomes blocked and accumulates bacteria with the years. It is really normal that it is dirty, it is used to filter the air that reaches you. There is no manufacturer's instruction on when to change it. We only advise you to disassemble it, check its condition. If it is completely dirty, it is better to replace it.
Resistance of the blower HS
If the ventilation buttons on the Nissan Maxima 4 are malfunctioning, or not at all, it is probably due to the resistance. This resistance used to increase the voltage to increase the speed of the turbine. A shady operation of the ventilation is probably due to a resistance malfunction. This small electronic chip is complex to repair. It must be replaced.
HS blower motor
There are several fairly common concerns about the kicker. The brushes are worn. As time goes by, these can deteriorate and produce electrical faults. The fan may run randomly, or may not spin at all. It is also possible that the malfunction is due to bearings of the fan motor. If the ventilation whistles, comparable to a rusty mechanism, it is possible that the bearings lack lubrication.
